What drives a watch's value
Brand and reference number come first, then condition, service history, and completeness. The original box and papers (the warranty card or certificate) add to the price because they help prove authenticity. Polishing can lower the value of collectible pieces if it softens the case lines.
Smartwatches behave like electronics: each new generation lowers what the older ones sell for.
Authenticity
Counterfeits are common at the high end. Buyers of luxury watches expect proof: papers, service records, or an authentication from a reputable dealer. A watch without them sells for less, if it sells at all.
